The CPM in West Bengal has allowed illegal immigrants from Bangladesh to freely enter India. Thus, the chunk of voters for these anti-national CPM and leftists are these illegal immigrants. The CPM has assured the illegal immigrants of full protection if they continued to vote for the Left (CPM and CPI and other left parties). This is how the left has managed to retain the power in WB. They start brain washing the children right from school against democracy and capitalism, thereby poisoning their minds. Almost all the schools in WB are in the custody of the CPM. And they call themselves patriotic...Allowing illegal immigrants from neighbouring countries is patriotism...
